This paper transmits a FORTRAN-IV coding of the fuzzy c-means (FCM) clustering program. The FCM program is applicable to a wide variety of geostatistical data analysis problems. This program generates fuzzy par
ClusteringThe fuzzy c-means (FCM) algorithm is a popular method for data clustering and image segmentation. However, the main problem of this algorithm is that it is very sensitive to the initialization of primary clusters, so it may not perform well in segmenting complex images. Another ...
Specify clustering options using an fcmOptions object. For this example, set the number of clusters to 2 and use default values for the other options. options = fcmOptions(NumClusters=2); Find the cluster centers using fuzzy c-means clustering. [centers,U] = fcm(fcmdata,options); Iteration...

模糊C均值聚类(Fuzzy C-means)算法简称FCM算法,是软聚类方法的一种。FCM算法最早由Dunn在1974年提出然后经 Bezdek推广。 硬聚类算法在分类时有一个硬性标准,根据该标准进行划分,分类结果非此即彼。 软聚类算法更看重隶属度,隶属度在[0,1]之间,每个对象都有属于每个类的隶属度,并且所有隶属度之和为 1,即更接近...
K-means和FCM模糊聚类算法的一个显著差别在于,K-means聚类是硬聚类(意思是一个样本要么100%属于A,要么100%属于B);而FCM模糊聚类算法则是软聚类(意思是一个样本有一定几率属于A,有一定几率属于B,但总概率为1)。 FCM(Fuzzy c-means)算法的基本过程:

1.Because the spatial information is not considered in the traditional fuzzy c-means(FCM) clustering algorithm,the serious inaccuracies with synthetic aperture radar(SAR) image segmentation can be caused by using the FCM algorithm.传统模糊c-均值聚类算法没有考虑图像像素空间信息特征,在应用于合成孔径雷达...
Fuzzy clustering has been useful in capturing the uncertainty present in the data during clustering. Most of the c-Means algorithms such as FCM (F
on original fuzzy c-means clustering algorithm,the improvement algorithm uses a new way of defining distance to displace the distance in Euclidean space.Experimental results show that the improvement algorithm is better than original algorithm and the classification is clearer than original algorithm. ...
